Letters Patent No. 99,338, dated February 1, 1870.

-IMPRovED PAINT-BRUS;

To all whom it may concern.-

Be it -known that I, GEORGE G. MORRIS, of Boston, in the county ofSu'olk, and State of Massachusetts, have invented an Improvement inFaint-Brushes; and I do hereby declare that the following, taken inconnection with the drawings, which accompany and form part of thisspecification, is a description of my inven-v tion, sufiicieut to enablethose skilled in the art to practise it.

In the man ufaoture of paint-brushes, it is customary to form a wirei'errule, by winding a c'oil of wire and soldering the adjacent wirestogether, thus making a ring or fer-rule, and to fill this fel-rule withthe but'ends of the bristles, driving through the centre of the bristlesin the ring the brush-handle, the large end of which compacts thebristles between it and the inner surface of the wire ferrule, the endsof the bristles being flush with the top of the ring, and being coveredwith cement.

Brushes have been made for many years with a circular cap interposedbetween ,the`ends of the bristles and the upper opening in the wireling, said cap being crowded into the end of the ring, and the ends ofthe bristles butt-ing against its inner surface. These caps hare beenmade of wood and of cork, and also of a cement composed of sand androsin, or sawdust and rosm.

Lately brushes have been, to some extent, manufactured having such capsmade of leather, as shown in the patent granted to D. \Vhite, November'24, 1868.

The only'dierence between the construction of suoli' White., and brushesmade for yea-rs previous' to said Vhites patent, being that said \Vhitesdisk or cap is made of leather, while in the previous brushes they weremade of wood, cork, or composition.

Inmy invention, I construct a brush with a disk or cap covering the topsof the bristles, such cap being made of pasteboard, applied in a moistor saturated condition, it being filled with a solution of shellac,which not only cements the bristles firmly in position, but causesthedisk or cap to become very hard, rigid, and impervious.

It is iu this construction that my invention consists, or in apaiut-brush having the bristles surmounted by a c ap made of pasteboard,permeated with shell-ae, and applied while in a pliant, moist, andviscid condition, the cap adhering firmly to the bristles when itbecomes dry, thereby not only strengthening the brush, but forming a capwhich is impermeable to the passage of the oil and turpentine containedin the paint.

The drawings represent a brush embodying my improvement.

A shows the brush in side elevation, the wires being broken away at onepoint to show the edge of the cap.

B is a sectional elevation ofthe brush.

a denotes the bristles;

b, the wire ferrule;

c, the handle; and

d, the cap. l

The bristles being properly prepared in the oustomary manner, and thebut-end of the bunch being placed in the ferrule, the ends are coveredwith a cement made of white lead, litharge, Sto. 'lhe pasteboard caphaving been prepared by soaking in the shellac solution, and being in asoft, visoid, and pliable condition, is pressed into the top oftheferrule, the bristles abutting against its inner surface. The point ofthe handle is then passed through the centre of the free ends of thebristles, and through the ferrule and cap, and isl driven up through thecap until the large end enters the cap-hole, and, expanding the cap,presses its periphery tightly against the inner surface of the cap.

The brush being then allowed to dry, the shellao and cement fasten thecap and bristles firmly in place, and the pasteboard becomes hard andimpermeable, as before set forth, not shrinking, as leather will do, un-

I der similar treatment, and not becoming pervious to oil andturpentine,l under the permeable action of which leather becomes soft,and soon breaks away from the cap and bristles.

I claim a paint-brush, having a cap, d, made of pasteboard, treated andapplied and rendered hard and impermeable, substantially as descrined.
